Versuchsvorschrift

In 40 ml of N,N-dimethylformamide was dissolved 3.0 g of 1-benzyl-4-[4-(2-pyrimidinylamino)benzyl]-2,3-dioxopiperazine, and 0.372 g of sodium hydride (purity 52%) was added thereto, after which the resulting mixture was subjected to reaction at 80° C. for 30 min. with stirring. The reaction mixture was then cooled, and 0.72 ml of chloromethylmethylsulfide was added thereto, after which the resulting mixture was subjected to reaction at 50° to 60° C. for 2 hours. After the completion of the reaction, the reaction mixture was distilled under reduced pressure and the residue thus obtained was extracted with chloroform and then washed with water. The solution thus obtained was dried over anhydrous magnesium sulfate, and the solvent was then removed by distillation under reduced pressure. The crystals thus obtained were recrystallized from isopropyl alcohol to obtain 3.0 g (86.45% yield) of white crystalline 1-benzyl-4-{4-[N-methylthiomethyl-N-(2-pyrimidinyl)amino]benzyl}-2,3-dioxopiperazine having a melting point of 156° C.
